Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Fixed gear Mountain Bike project

All,

I have a crazy desire to make a fixed gear mountain bike as the ultimate urban winter commuter bike. I have a chance to buy a Raleigh M50 for $50 that's in good shape (not sure of the year) but I can't tell if the rear dropouts are horizontal enough for a proper fixed gear conversion. It looks to be similar to this dropout from Sheldon Brown's page on fixed gear conversions.

Can anyone make a recommendation based on the above info? It's been pretty hard to find a mtb bike with horizontal dropouts. I'm familiar with the ENO hubs, but am trying to make this project cost as little as possible to I can save up for my new tri bike.

Thanks!

If it has dropouts like the one you pictured, then it will be a piece of cake. Really, all you need is about a 1/2" of horizontal movement to get what you want.

BTW, I happen to think that older MTB's (with horizontal drops) make a fantastic, tough, and cheap fixed gear bike platform. They make killer urban/utility/winter bikes especially. I would not trade my fixed Rockhopper for anything.

My first fixed conversion was with an old MTB. Had that same style drop outs, thing was a beast. Took some getting used to, trying to skid was a bit-o-fun though.

When it comes to tires, I recommend Kenda KRads for such a machine.

I am pretty partial to Schwalbe Big Apples on such a beast. If you are going to go tough, go real tough.

I have a fixed Surly Karate Monkey I ride in winter.

I call it the Ice Bike.

Summer, when in the mood, I ride it with Schwalbe Big Apple tires, and during the winter, with ice and snow, I ride it with Nokian 294's.

The Karate Monkey has horizontal dropouts:

I did something similar to this with my old Spec Rockhopper. Dropouts are the same.

Hardtail Rockhopper => fixie
